Manufacturing Process

At Gotrays, our Cordierite-Mullite refractory plates are made with care and precision. We start by mixing top-quality raw materials: mullite clinker, talc, and kaolin. This blend ensures the right balance of strength and thermal shock resistance.

Next, the mixture goes through extrusion or pressing to form the plates in the desired shape and size. After shaping, the plates are fired at a high temperature of 1350°C. This sintering process locks in the material’s durability and heat resistance, perfect for demanding kiln applications.

To make sure you get a reliable product every time, we follow strict quality controls. Our plates undergo ISO-certified testing, including phase purity checks with XRD analysis, to guarantee consistent performance and long service life.

Customization Options

We understand every kiln setup is different. That’s why our Cordierite-Mullite Refractory Plates come with flexible customization options to fit your needs:

• Grooved and perforated designs for better airflow and heat distribution
• Sagger integration to match your existing kiln furniture system
• Kit assemblies including plates plus supports, ready to install
